I think more than half the people on twitter are paid by Soros. That’s why they always flood Trump’s tweets. Remember the Krassenstein bros? They’re still on there, just under new accounts.
Honestly, there are enough “followers” in the world who are so rabid they simply need to be given a nudge. No need to pay them.
Trolls are all over the internet.
I understand that computers can do the job faster and cheaper. We get several hundred calls a day as msgs and just delete them and the same number pops up later. The same mechanism is used elsewhere for other purposes. Humans just program what they want for as frequently as they want.
